AIR-DRUM SUPPORT FOR LOCOMOTIVES.

Application filed November 28, 1925. Serial No. 72,004.

One object of my invention is to provide means for supporting the air drums inde pendently of the locomotive boiler, so as to relieve the boiler from strain at the studs which usually secure the supporting brackets of the air drums to the, boiler.

A further object of the invention is to utilize the waist-sheets of the locomotives for supporting the air drums.

In the accompanying drawing:

Fig. 1 is a side elevation of a portion of a locomotive;

Fig. 2 is atransverse section of a locomotive taken on the line 2-2, Fig. 1,-sh0wing the waist-sheets and the air drums carried independently of the boiler; and

Fig. 3 is a perspective view of the air drum supports which are secured to the waistsheet.

1, 1 are the side frames of a locomotive. 2, 2 are the waist-sheets which are secured to cross members 3 of the frame in the ordinary manner. 4 is the locomotive boiler. 5 is a curved angle-iron which forms a saddle for the support of the boiler. This saddle may be secured by rivets or studs to the 'Fboiler, and to the waist-sheet by a series of bolts as shown.

The waist-sheet has extensions 6 at each side which form brackets to which the air drum supports '7 are attached by a series of bolts 8. Each bracket has a curved seat 9 for an air drum l0, and straps 11 extend over the air drum. The ends of these straps are threaded and passed through openings 12 in the supports, and nuts 13 are mounted on the threaded portions of the straps so that on turning the nuts, the straps draw the drums firmly onto the seat.

It will be noted that the. air drums or their supports are not attached to the boiler, so that any vibration of the air drum will not affect the boiler,

\Vhile I have shown an air drum on each side of the boiler, 1n some instances only an air drum may be mounted on one side, without departing from the essential features of the invention.

I claim:

l. The combination in a locomotive boiler; a waist-sheet supporting the boiler; and

straps securing the air drums to the supports.
